Understanding the Assertion and Reason
The statement consists of two parts: an assertion (A) regarding AIDS and a reason (R) related to its causative agent, HIV.
Assertion (A)
- A person suffering from AIDS has a severely weakened immune system.
- This condition makes them vulnerable to infections, even minor ones, which they would typically be able to fight off.
Reason (R)
- The reason provided states that the casual organism of AIDS is HIV (Human Immunodeficiency Virus).
- HIV attacks and destroys CD4 cells (T-cells) in the immune system, leading to the condition known as AIDS.
Evaluation of the Statements
- Both assertion (A) and reason (R) are correct.
- The assertion accurately describes the immune deficiency experienced by individuals with AIDS, leading them to be susceptible to infections.
- The reason correctly identifies HIV as the virus responsible for causing AIDS.
Correct Explanation Analysis
- While both statements are true, the reason (R) does not specifically explain why persons with AIDS cannot fight infections.
- The reason explains the causative agent but does not directly correlate to the impact on the immune system's ability to combat infections.
Conclusion
- Therefore, the correct option is (b): Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
